A series of Pictet-Spengler condensation derivatives (tetrahydro-beta-carbolines) was designed, synthesized and evaluated for lethality against a panel of seven cancer cell lines. Seven compounds (2a, 13, 20, 21, 27, 29 and 34) showed lethality in at least five cell lines. Among these, compound 27 showed a unique selectivity towards oncogenic-RAS expressing BJ-TERT/LT/ST/RAS(V12) tumor cells, compared to non-transformed BJ-TERT cells. Further investigation revealed that 27 induces cell death without activation of caspases. This represents a useful new probe of non-apoptotic cell death and oncogenic-RAS synthetic lethality.
